Platysodes formosanus Kobayashi, 1990

( Figs. 1–5 , 42 )

Platysodes formosanus Kobayashi, 1990: 78 (type locality: Mt. Nanfengshan, Maolin, Kaohsiung, Taiwan), figs. 4 & 8 ♂ (parameres and holotype); Sakai & Nagai 1998: 163 (Puli, Taiwan), plate 5, fig. 111 ♀; Yu et al. 1998: 100, plate 5, fig. 13 ♂ (holotype); Krajčik 1999: 43; Smetana 2006: 300; Krajčik 2012: 213.

Diagnosis. This species is similar to P. jansoni . The primary difference is the presence of a small, velvety white macula in the middle of the elytron near the lateral margin, which is absent in P. jansoni .

Type material examined. Holotype of Platysodes formosanus Kobayashi, 1990 is labeled: “ HOLOTYPE [P.], Platysodes formosanus [H.] H. Kobayashi [P.], (1990) [H.], [red label with black border]/ Nanfengshan, Maolin, Taiwan [P.], May 10 [H.] 1986, Ching-Kin Yu leg. [P.], [white label]” (♂, MSMT, Figs. 1–5 ).

Comments on type material. Platysodes formosanus was described by Kobayashi based on a single male specimen, and it is preserved in his personal collection as he indicated in the original publication ( Kobayashi 1990). However, the holotype was not found in a recent search (Mr. Hirokazu Kobayashi, personal communication). As indicated in the original description, the holotype was collected by “ Y. Ching” (incorrect spelling of Ching-Kin Yu) from Mt. Nanfengshan in Kaohsiung Hsien, Taiwan. The late Mr. Ching-Kin Yu (1926– 2012) was curator of the collections of MSMT where a considerable number of his specimens are deposited, the holotype of P. formosanus may also preserved there. This supposition later was confirmed by our colleague, Mr. Yu-Tang Wang, who found a male specimen with a holotype label is perfectly in accord with the original publication.

Other material examined. Taiwan 1♀ ( NSMT), 10.VI.1965, Hori [Puli], Formasa [sic!] / Plastodes formosanus [sic!]; 1♂ ( MFCJ), 7.IX.2008, Shizitou, Puli, Nantou, native leg.; 1♀ ( WICC), 15.X.2006, Siji, Datong, Ilan Hsien, alt. 1000m, Yu-Wei Huang leg.; 1♂ ( WICC), VII-2008, Qishan, Kaohsiung Hsien, Qi-Han Gao leg.

Distribution. Taiwan.

Remarks. Platysodes formosanus is endemic to Taiwan, and only five specimens are known to us. Both bear only one small, white macula in the center of the elytron near the lateral margin.
